Re: Update HADOOP as updates occur via SLT

Two ways that are easy

 

- Enhance the SLT table via IUUC_REPL_MON, add logic for timestamp to be added to record when it's processed by SLT. Then have the Sqoop job use that timestamp for delta tracking, pulling only data >= timestamp

- Have HANA maintain the timestamp via calculated column; GENERATED ALWAYS AS X and have the current timestamp. Sqoop processes the same way from here.

 

Probably more transparent with the first option.

 

As far as I know there is no support for writing directly from SLT to Hadoop, but it was mentioned that you could possibly invoke a webservice in ABAP layer when SLT is processing the record - but it was very tricky. Might get more developed as time goes on, but the above should work no problem.

Justin
